I have been playing with cryptocurrencies for 3 years now, one of the biggest lessons i learned is cryptocurrencies move very quickly. With how fast steemit has gone up it can go down just as fast. I would do you best to fully understand steemit and decide if you think it has a long term future. Do your best to make that decision without thinking about how fast its going up because if anything goes wrong it could come down just as fast just like the dao.
